SAMUEL W. REYNOLDS, OF WEST TOLEDO, OHIO.

SPOT-SETTER.

Specification of Letters Patent.

Patented June 29, 1909.

Application filed May 8, 1907. Serial No. 372,594.

To all whom it may concern:

Be it known that I, SAMUEL W. RnYNoLns, a citizen of the United States,residing at West Toledo, in the county of Lucas and State of Ohio, haveinvented a new and useful Improvement in Spot-Setters, of which thefollowing is a specification.

My invention relates to improvements in spot setters.

This invention has for its primary object a device of its kind which canbe used to set spots or rivets of various sizes and designs upon thesurfaces of leather or other suitable material by hand at suitabledistances apart with accuracy and precision.

Further objects aresimplicity of construction and effectiveness in use,thus rendering the device inexpensive and easy to manipulate.

Generally speaking, my invention comprises a suitable anvil frame onwhich a spring arm is carried, and a hand-operated setter which isadapted to pass through said frame and secure spots or rivets to theleather or other material at random or fixed spaces apart.

My invention further consists of the features of construction andcombinations of parts hereinafter more particularly described andclaimed.

In the accompanying drawings, forming part of this specification, Figure1 is a plan view of my invention, Fig. 2 is a side view of Fig. 1showing the setter tool partly broken away; Fig. 3 is a sectional viewof one of the thimble holders; Fig. 4 is a plan view of said thimbleholder Fig. 5 is an enlarged detail sectional view showing the settertool in the act of driving a spot through a strip of leather or othersuitable material; Fig. 6 is another sectional view showing the parts inposition when a spot or other rivet has been secured to the leather orother suitable material, and Fig. 7 is a side view of one of the spots.

In the drawings A represents a suitable anvil frame and B a swinging armabove said anvil frame which is pivoted thereto at C between the posts2. The swinging arm is formed with two or any suitable number ofopenings 3 and 4 which are adapted to re ceive thimble holders for spotsor rivets such as illustrated by 5 in the forward opening 8. Thesethimble holders may be of various sizes and designs so as to set spotsor rivets of corres onding shapes and sizes. The form of thimb e holdershown is adapted for setting the creased circular headed spot shown inFig. 7, but it is obvious that this invention is equally applicable foruse in setting any shaped spot or rivet desired. The object of formingthe arm 13 with two places for receiving the thimble holders is so as toin crease the range of sizes to which the setter is applicable. Theopening 3 as illustrated is adapted to receive thimble holders of threedifferent sizes and the opening 4 to receive thimble holders of threeother larger sizes. These thimblc holders are provided with a circularshoulder 6 which is received upon an edge surrounding one of itsopenings 3 or 4. The inner wall of the upper end of the thimblc holderis provided with downwardly and inwardly inclined slots 7 by which theshanks 8 of the spot are received and guided into the thimble and thespots held from turning.

The thimble spot holders are held in the openings 3 and 4 by means ofthumb screws 9 which impinge against the outer walls of the thimble spotholders through the swinging arm to hold said holders in place. Theopening 10 in each'thimble spot holder as shown is substantiallycylindrical in shape and adapted to receive a cylindrical or othershaped set tool D of any suitable size therein. The lower portion ofeach set tool corresponds in diameter with the inner diameter of theopening in its thimble holder mate and is provided with a recess 11 inits end for the purpose of forming a circular edge 12 which impingesagainst the circular edge of the head of the spot to attach the latterto the leather. The depth of the recess is suflicient to space the settool away from the head of the spot or rivet, thus avoiding all dangerof marring or injuring the surface of such head. It is obvious that theset tool may set firmly over the entire surface of the head whendesired.

Immediately below the thimble holder in the anvil frame A are threeconcentric grooves 13, the larger one coinciding with the lower end ofthe thimblc spot holder immediately above it and the next smaller andsmallest grooves coinciding respectively wlth the smaller thimblc spotholders when used and in a similar manner as the first one. Thesegrooves appear in cross section as curved so as to guide and turn inwardthe shanks 8 of the spot on the lower side of the leather when the settool is driven home.

Between the anvil frame and the swinging arm B is a longitudinal gage Ethe face plate 14 of which is carried upon a longitudinal rod 15 whichpasses through the end 16 of the anvil frame and is set inlongitudinally adjusted p means ot' the thumb bolt 17, t e inner endwhich impinges against said rod. lower edge of the face plate 14 re ts eat re and thus prevents turning and i 'ded with a {L079 a groove 18 t Iin wince e 1 ter heing or tne spaced leat U L with seal with its shanksp si the leather or other meteria In accordance with the a I havedescribed *he prinei e of my invention, together with r i 'us which Inow consider to represent tne embodiment thereof, but I desire to haveit understood that the apparatus shown is only illustrative and that theinvention can be carried out by other means and applied to uses otherthan those above set forth within combination, an anvil frame having asn arm pivoted thereto in a plane above the same and provided with aplurality of openings, tl *nble holoers of different sizes i saidopenings and having circular shoulders resting on the edges of saidopenin s and longitudinal slots in their walls to admit the shanks ofspots to prevent them from turning, thumb screws through the walls ofthe "frame and impinging against the thim le holders to hold the latter,said holders being adapted to be mated with set tools having deeprecesses, a rod passing longitudinally through the end of the anvilframe, a main plate having a transverse groove in face carried by saidrod, a transverse gage on srld main gage and in said groove, and setscrews holding said rod and transverse in set positions, for thepurposes specified.

In testimony whereof, I have signed my name to tl is specirication, inthe presence of two subscribing witnesses.
